Description
Bandförderer für Trockner Die Erfindung geht aus von einem Bandförderer für Trockner, dessen Plattenband dadurch gebildet wird, daß dünne, biegsame Platten durch Querstege mit endlos umlaufenden Kettenpaaren verbunden sind.Belt conveyor for dryer The invention is based on a belt conveyor for dryers whose apron conveyor is formed by thin, flexible plates are connected by crossbars with endlessly revolving chain pairs.
Derartige Bandförderer haben den Nachteil, daß die Platten an den Umlenkstellen ein Vieleck bilden, wodurch das Gut, wenn mehrere Bandförderer übereinander angeordnet sind, in einzelne Haufen auf den jeweils darunterliegenden Förderer abrieselt. Die Folge ist eine ungleichmäßige Gutsverteilung und hierdurch bedingt eine ungleichmäßige Abtrocknung des Gutes. Ist das Förderband perforiert ausgeführt und wird die Trocknungsluft gezwungen, durch die Lochungen und das Gut zu strömen, so bringt die ungleichmäßige Gutsbelegung den weiteren Nachteil mit sich, daß sich die Luft den Weg des geringsten Widerstandes sucht, d. h. an den Stellen das Förderband durchströmt, an denen kein oder wenig Gut liegt. Hierdurch wird die Ungleichmäßigkeit in der Abtrocknung des Gutes noch unterstützt, außerdem erhöht sich der Abgasverlust. Such belt conveyors have the disadvantage that the plates on the Deflection points form a polygon, which makes the good when several belt conveyors are on top of each other are arranged, trickles down into individual piles on the respective underlying conveyor. The result is an uneven distribution of the material and, as a result, an uneven distribution Drying of the goods. If the conveyor belt is perforated and is the drying air forced to flow through the perforations and the material, so brings the uneven Gutsbelichtung the further disadvantage with it that the air is the way of the least Seeks resistance, d. H. flows through the conveyor belt at the points where no or little good lies. This reduces the unevenness in the drying of the The good is supported, and the exhaust gas loss increases.
Es ist auch bekannt, endlose Bänder eines Fördereres an den Umlenkstellen in einem Halbkreis umzubiegen. Die Umlenkung erfolgt über Trommeln. It is also known to have endless belts of a conveyor at the deflection points bend in a semicircle. The deflection takes place via drums.
Diese Konstruktion führt unter anderem deshalb nicht zu einem befriedigenden Ergebnis, weil sich auf den Umlenktrommeln Gutansätze bilden, die schon nach kurzer Zeit Betriebsstörungen hervorrufen.Among other things, this construction does not lead to a satisfactory one Result, because deposits of goods form on the tail pulleys, which after a short time Time cause malfunctions.
Zur Vermeidung dieser Nachteile geht die Erfindung von einem Bandförderer für Trockner der eingangs ausgeführten Art aus und ist dadurch gekennzeichnet, daß die Platten beidendig auf den als Holme ausgebildeten Querstegen durch starre Verbindung (Niete, Schrauben, Schweißen) zu einem endlosen Band zusammengefügt sind, das an den Umlenkstellen in einen exakten Halbkreis dadurch umgebogen wird, daß das Band auf der Oberseite der Holme festgelegt ist, die in der Mitte zwischen den Kettenbolzen an den Kettenlaschen befestigt sind, wobei die Oberkante jedes Holmes über der Achse der Kettenbolzen liegt, so daß sich in dem vom Band gebildeten Umlenkbogen stets mindestens drei Holme befinden und der Halbkreisumfang des Umlenkbogens ein exaktes Vielfaches der Kettenteilung und der Stegteilung ist. Hierdurch wird an der Umlenkung der Abstand der Holme verkürzt und die zum Ausbiegen der Platten erforderlichen Kräfte werden über die starre Verbindung mit den Holmen auf die Platten übertragen. To avoid these disadvantages, the invention is based on a belt conveyor for dryers of the type set out above and is characterized in that the plates at both ends on the crossbars designed as spars through a rigid connection (Rivets, screws, welding) are joined together to form an endless band that is attached to the turning points is bent into an exact semicircle by the fact that the tape is fixed on top of the spars, which is in the middle between the chain pins are attached to the chain links, with the top of each spar above the axle the chain pin lies so that there is always in the deflection curve formed by the belt at least three bars are located and the semicircular circumference of the deflection arch is exact Multiples of the chain pitch and the web pitch is. This is at the deflection the distance between the spars is shortened and the ones required to bend the panels Forces are transferred to the plates via the rigid connection with the bars.
Zweckmäßig ist es, wenn sich die Enden der biegsamen Platten an den Verbindungsstellen überlappen und die unmittelbar auf dem Holm aufliegende Plattenkante nach innen umgebogen ist. Nach einem weiteren Vorschlag soll der Holm ein U-förmiges Profil aufweisen. It is useful if the ends of the flexible plates on the Overlap connection points and the plate edge lying directly on the spar is bent inwards. According to another suggestion, the spar should be U-shaped Have a profile.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel erläutert. Hierin zeigt F i g. 1 einen Mehrbandtrockner im Schema, F i g. 2 die Umlenkstelle des Förderbandes, F i g. 3 einen Schnitt nach Linie A-B in F i g. 2, Fig. 4 eine Ansicht von C in Fig. 2, jedoch ohne aufgelegte Bleche, und Fig.5 einen einzelnen Quersteg mit hieran befestigten Blechen. The invention is explained in the drawing in an exemplary embodiment. Herein, FIG. 1 a multi-belt dryer in the scheme, F i g. 2 the turning point of the conveyor belt, F i g. 3 shows a section along line A-B in FIG. 2, Fig. 4 a View of C in Fig. 2, but without applied sheets, and Fig. 5 a single one Cross bar with metal sheets attached to it.
Endlos umlaufende Kettenpaare 1 sind durch als Holme ausgebildete U-förmige Querstege 2 miteinander verbunden. Beidendig auf den Holmen sind einzelne gelochte, dünne, biegsame Bleche 3 durch Niete zu einem endlosen Band zusammengefügt. Endlessly revolving chain pairs 1 are designed as spars U-shaped transverse webs 2 connected to one another. There are single ones on both ends of the stiles perforated, thin, flexible sheets 3 joined together by rivets to form an endless band.
Fig. 5 zeigt eine solche Verbindungsstelle. Wie ersichtlich, überlappen sich die Blechenden. Die unmittelbar auf dem Holm aufliegende Blechkante ist nach innen abgebogen. Das endlose Band wird an den Umlenkstellen in einen exakten Halbkreis dadurch umgebogen, daß das Band auf der Oberseite der Holme festgelegt ist, die in der Mitte zwischen den Kettenbolzen 4 an den Kettenlaschen 5 befestigt sind, wobei die Oberkante jedes Holmes über der Achse der Kettenbolzen liegt (Abstand a) und daß sich in dem vom Band gebildeten Umlenkbogen stets mindestens drei Holme befinden und der Halbkreisumfang L des Umlenkbogens ein exaktes Vielfaches der Kettenteilung t und der Stegteilung tl ist.Fig. 5 shows such a connection point. As can be seen, overlap the sheet ends. The sheet edge lying directly on the spar is behind bent inside. The endless belt turns into an exact semicircle at the deflection points bent in that the tape is fixed on the top of the spars, the are fastened to the link plates 5 in the middle between the chain pins 4, with the upper edge of each spar above the axis of the chain pins (distance a) and that there are always at least three spars in the deflection curve formed by the belt and the semicircular circumference L of the deflection arch is an exact multiple of the chain pitch t and the web division is tl.
